CARBONITRIDING OR CEMENTATION STEEL AND METHOD OF PRODUCING PARTS WITH SAID STEEL

摘要

The invention relates to a carbonitriding or cementation steel and to a method of producing parts with said steel. According to the invention, less than 0.15 wt.- % vanadium is incorporated into a carbonitriding or cementation steel, which, together with a specific composition for the remaining elements, serves to increase the hardenability of the steel and to minimise deformations when a surface area of a part to be produced with said steel is subjected to a cementation or carbonitriding hardening treatment followed by hardening in a mild medium.
